JAMES H. VENNERS.l OF BROOKLYN, NEW YORK. A

WATER-PRESSURE INJECTOR.

SPECIFICATION forming part'of Letters Patent No. 761,021, dated May 24, 1904. i Application filed June 7, 1902. Serial No. 110,694. (No model.)

To all whom, it mfG/y con/cern.-

Be it known that I, JAMES H. V'ENNnRs, a citizen of the United States, residing at'Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Water-Pressure Injectors, ofwhich the following is a specification.

My invention has relation to improved means for chemically charging water mains or pressure pipes with disinfecting or antiphlogistic solutions.

The invention is particularly adapted for connection to urinals and basins having no flush-tanks associated therewith and also for sprinkling floors and applications to garbage to prevent or destroy the deleterious efects thereof.

The object of the invention is to provide an apparatus embodying a vessel charged with a chemical solution and provided with a feed pressure-pipe leading from the main into the upper portion of the vessel and a dischargepipe to carry thesolution back into the main and thence through the main to the point required.

I`t is also the object to provide an apparatus .for the purposes intended which is of simple construction and is eiicient and durable in use.

The apparatus may be readily arranged in operative position in connection with the main water-pipe to feed the disinfecting or antiphlogistic solution to the places to be acted upon.

l/V ith these purposes in View my invention consists in the novel construction of the apparatus andthe aggroupment of the parts in operative combination, as will hereinafter be fully described and the novelty thereof be particularly pointed out and distinctly claimed.

I attain the objects by the means illustrated in the accompanying drawings, in which similar reference-notations indicate similar parts throughout both views, and .wherein- Figure l is a view of the complete device in side elevation, showing it as connected to a main water-conduit pipe. Fig. 2 is a detail plan view of the perforated disk removed from its seal in the vessel.

Referring to the drawings, A designates a cylindrical vessel or casing made of suitable non-corrodible material andof such dimenthe main water-pipe 4. In the pipe 2 is mounted a valve 5 of any proper construction,` whereby the iiow of the chemically-charged solution from the vessel may be regulated to suit the desire or by which the iiow may be entirely shut off. Ata proper location in the vessel is an annular fiange 6, on which is seated a perforated plate 7, dividing the vessel into two compartments and constituting the bottom of the chamber wherein the chemical material is contained and also a partition between this chamber and the chamber below it wherein the charged solution is deposited and held.

8 designates a by-pipe serving as the waterfeed pipe opening from the main pipe 4t and extending vertically and then horizontally, as at 8a, opens into a neck-piece 9, which opens into the vessel A through the cover 10, substantially as shown in the drawings, the purpose being to convey the requisite quantity of water to the material-chamber l1 to permeate, saturate, or dissolve the material therein and then pass out of the chamber through the perforated plate into the Huid-chamber below charged with the chemical. To regulate the flow of water through the pipe 8, a valve 12 is placed at any convenient point therein. vAs heretofore indicated, the device is designed for injecting a charge of disinfectant into a moving stream of water used to cleanse and purify urinals', water-basins, closets, and similar appliances at desired times and as occasions may require, it being understood that except at the times when the water in the main pipe is being used for the purpose mentioned it is at rest in the pipe, so that when the Valve l2 is opened the pressure in the main pipe will force the water up the pipe 8 and into the chamber 11 onto the chemical material therein. Thence the water percolates through the chemical material and falls IOO perforated plate 7, rising upward in this chamber until the desired quantity has accumulated, when the flow is stopped by cutting it off at valve 12. Now when it is desired to use the accumulated charged fiuid in the vessel a valve in the main pipe is turned to start the water coursing therethrough, and at the same time the valve 5 is opened to permit the chemical solution to discharge by gravity into the main pipe. After the iiushing and disinfection have been accomplished the water in the main pipe is cut off and the valve 5 closed. The Valve 12 may then be opened and the vessel again charged anew, the valve 1Q being againpclosed, when the charge is completed.

To the neck-piece 9, opening' through the cover of the vessel A, is connected a valvechamber 13, in which is arranged a suitable valve, the upper end of the valve-chamber being secured to the bottom of a charging-tank 14 and opens therein. The tank 14 is of such capacity as may be required to keep a sufcient supply of material ready to be let down through the valve 13 into the chamber 1,1.

A charging pipe or funnel 15 is mounted on the tank 14 and opens into it. rlhe pipe 15 is provided with a valve 16, which is opened and closed as occasion requires. A drip-cock 17 is provided in the tank 14, whereby any deposits may be drawn ofi'.

1t will be perceived that if the tank 14 is charged with a disinfectant or with an antiphlogistic material it will on opening the valve 13 automatically pass by gravity down into the chamber 11 until the requisite quantity has been served, when the valve 13 may be closed.

The functions of the parts have been stated in connection with the description of them; but the operation may be now rehearsed and stated, as follows: The tank 14 may be first charged and the material then permitted to descend through valve 13 into the chamber 11 until the required quantity has been deposited into the larger chamber below the stationary l therein, when the valve 13 can be closed and the charge into tank 14 continued until it is filled ready for future use. The valve 12 may then be opened and the water left free to rise through pipe 8 and discharge on the material in the chamber 11, through which it percolates and descends through the perforated plate 7 into the lower chamber of the vesselA and there accumulates. The valve 12 is now closed. Now when it is proposed to charge the water in the main with the charged iuid in the vessel the main pipe is opened and Athe valve 5 is opened and the chemicallycharged` contents are injected into the main with accumulated force, as heretofore specified.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination with a water-supply pipe, of a vessel having a stationary perforated partition dividing the same into an upper compartment for holding a soluble chemical substance, and a lower compartment for holding a solution of such substance, a valved waterfeed pipe rising from the supply-pipe, and communicating with the upper compartment to discharge water onto the chemical substance therein, a valved connection between the bottom of the lower compartment and said supply-pipe, a valve-chamber mounted on top of the vessel, and provided with a valve, and a feed-tank mounted in turn upon said valvechamber and provided with a hopper, the said tank being provided with a draw-off cock, and the said hopper having' a valve for opening and closing communication between the same and the tank.

In testimony whereof I afliX my signature in presence of two witnesses.

JAMES H. VENNERS.
